CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 510,660, dated December12, 1893. Application filed October 4,1893- Serial No. 487,175. (Nomodel.)

To all whom it may concern:

Be it known that 1, WILLIA C. Wnrsoiv of Paterson, in the county ofPassaic and State of New Jersey, have invented a new and usefulImprovement in Car-Couplings, of which the following is a specification.

This invention relates to that class of couphugs the principal elementsof which are books pivoted and having lateral movements Within thedraw-heads, the coupling action being effected by the engagement of twosuch hooks one on each of two cars to be coupled.

I will describe in detail a car-coupling embodying my improvement andthen point out the novel features in the claims.

Figure 1 in the accompanying drawings is a plan view, partly in section,of one member of a car-coupling embodying my invention. Fig. 2 1s a sideview of the same. Fig. 3 is a front view of the same.

Similar letters of reference designate corresponding parts in all thefigures.

A is the draw-head of the hollow construction common to couplings of itsclass and having pivoted within its rear part the rear end of the shankB of the coupling-hook B, the said hook being pivoted by a pin a to thedrawbar 0 and being capable of a limited sliding movement in slots 0provided in the top and bottom of the draw-head as indicated in dottedoutline 'in Fig. 1. The front end of the draw-head is closed as shown atcl, on that side toward which the hook moves for-coupling and has anopening in the other side as shown at e e 111 Fig. 3, to permit themovement ofthe hook in a direction for uncoupling, and in order to keepthis opening closed the coupling-hook B has provided on its back alateral wing f shown in Figs. 1 and 3, the said wing sliding across theface of the draw-head over said opening (2 e. A spring 0 is appliedwithin the draw-head to act upon the coupling-hook to keep it constantlypressed in a direction for coupling.

H I J designate a lever for pushing aside the coupling-hook B foruncoupling, the said lever being pivoted into the draw-head by a pin g,which constitutes its fulcrum, not being connected with thecoupling-hook but being arranged to move the said hook aside by simplypressing against it, the said lever projecting through and from thedraw-head sothat it may be operated by hand by a man standing at theside of the car without going between two cars. This lever isrepresented in Fig. l as of peculiar form having a T-head I J from nearthe middle of which the arm H to which the power is applied is projectedin the form of a hook is from which it is extended in any form, asstraight, convenient for operation. The lever thus constructed, so faras its operation is considered, is like that of an elbow-lever of whichthe arm H to which the power is applied, would be extended in onedirection directly from the fulcrum g and the other arm at the end ofwhich is the point of application J, would be extended in anotherdirection directly from the fulcrum.

The object in making the lever of the .T- headed and hooked form abovedescribed is to facilitate its insertion into the hollow drawhead which,if it were in the form of an ordinary elbow lever, would require moreroom than could conveniently be provided within the draw-head betweenthe shank of the coupling-hook and the side of the draw-head. To providefor the insertion of the head I J of this lever into the draw-head, along slot Z is provided in the side of the draw-head in front of thefulcrum 9. To insert the lever the end I of its hooked portion is firstinserted through the slot with the arm H nearly parallel with the sideof the draw-head and then by gradually drawing out the said arm H andpushing back the head I J of the lever the end I of the head is broughtinto a suitable position to permit the fulcrum pin g to be droppedinthrough the openings provided in the drawhead and the leverrespectively.An opening .011 is also shown in the draw-head opposite the fulcrum g,but this opening is immaterial.

' To operate the coupling-hook by the method above described the arm Hof the lever which is accessible from the side of the car is pulledtoward the outer end of the draw-head. When this leveris released thespring always throws the hook into the coupling position. If, however,it should be desired to provide for the operation of the uncouplinglever H I Jfrom the platform or roof of a car, such provision may bemade by means of a crank or cam applied to said lever in connection withan upright shaft and hand wheelin amanner which is common and Wellunderstood.

\Vhat I claim as my invention is- 1. In a car-coupling, the combinationof a hollow draw-head, a couplinghook having its shank pivoted in therear portion of said drawhead, and an uncoupling lever pivoted in andprojecting laterally through and from the draw-head and bearing againstone side of the said hook for the purpose of pushing aside the saidhook, substantially as herein set forth.

2. The combination with the hollow drawhead havinga slot Z on one side,the couplinghook B B pivoted Within the said draw-head to move laterallytherein and a T- headed hooked lever H I J passing through said slot Zand having its fulcrum g in the said draw-
